The AUS 200 is a stock market index that represents the performance of the top 200 companies listed on the Australian Securities Exchange (ASX). The index is also known as the S&P/ASX 200 and is considered the benchmark index for the Australian equity market. The AUS 200 is a market-capitalization-weighted index, which means that larger companies have a greater impact on the index’s performance than smaller companies. The index covers a range of industries, including financials, materials, energy, and healthcare. As a result, the AUS 200 is often used as an indicator of the overall health of the Australian economy and the performance of its major industries. The AUS 200 is frequently traded through derivative products such as futures and options, and forex traders may also use it as a benchmark to compare the performance of Australian stocks against other global equity markets.
